96Boards compliant Rock960 board launched last year for $99 with Rockchip RK3399 processor, 2 to 4GB RAM, 16 to 32GB eMMC flash for $99 and up. However, now you can buy a Rockchip RK3399 SBC for as low as $45 plus shipping thanks to FriendlyElec NanoPi NEO4 board that comes with 1GB RAM and no built-in storage, relying instead on a micro SD card slot or eMMC socket. So VAMRS decided to design a cheaper version of their board with Rock960 model C that still benefits from being part of the 96boards ecosystem, is equipped with 1, 2 or 4GB LPDDR4 RAM, and the OS can boot from a micro SD card or an optional eMMC flash module. The 1GB version of the board is now sold for $69 on Seeed Studio with shipping scheduled for the 1st of February 2019. Rock960 model C preliminary specifications: SoC – Rochchip RK3399 hexa-core big.LITTLE processor with 2x Cortex A72 cores up to …

Portable displays have been available for a while, but they used to be fairly heavy, as for example, Gechic On-Lap Monitor 2501M 15.6″ portable monitor weighted 1.3 kg with cover. However in recent times, we’ve seen several such products – LAPSCREEN and DUO Add-on Display – launched with lighter designs, and the advance as USB type-C and power delivery make those even more attractive since a single cable can be used to transfer video, and power both the display and the host device. TAIHE Gemini is yet another option, but at 15.6″ is larger than the two aforementioned products, it is equipped with its own battery and kickstand, and comes in two variants with either 1920×1080 Full HD or 3840×2160 (4K UHD) resolution. TAIHE Gemini FHD & UHD portable displays specifications: Display Gemini FHD – 15.6″ 10-point touchscreen IPS display with 1920×1080 resolution, 15ms response time, 180° kickstand Gemini UHD – 15.6″ IPS display with 3840×2160 resolution, 14ms response time, …

When Shenzhen Xunlong Software launched their first Allwinner H6 development board, Orange Pi One Plus, many were disappointed as the board did not make use of some of the key features of H6 processor like USB 3.0 or PCIe, and RAM was limited to 1GB. A couple of weeks later, the company introduced Orange Pi Lite2 board with 802.11ac WiFi, a USB 3.0 port, HDMI 2.0a output, but no Gigabit Ethernet, nor PCIe interface, and again only 1 GB LPDDR3 memory. The good news is we now get a full-featured Allwinner H6 SBC thanks to Orange Pi 3 equipped with up to 2GB RAM, an optional 8GB eMMC flash, Gigabit Ethernet, 802.11ac WiFi 5, four USB 3.0 ports, HDMI 2.0a, a mPCIe slot, and more. There are four variants of the Orange Pi 3 board with either 1 or 2 GB RAM, with or without eMMC flash that share the following specifications: SoC – Allwinner H6 V200 quad-core Cortex A53 …

5G has yet to really take off, as it’s only available in a few cities, but a recent report publishes by Ericsson provides some forecasts for the future of 5G and cellular IoT connectivity, as well as interesting numbers of the current state of cellular networks. There are now 7.9 billion mobile subscriptions, more than humans, including 5.7 billion mobile broadband subscription, with Asia clearly dominating the field due to its much larger population. Asia also accounts for most of the recent growth in subscriptions, and interestingly people in Central and Eastern Europe (including Russia) especially appears to need more than one mobile subscription with 142% penetration, which means on average one person has 1.4 mobile subscriptions. There are more subscriptions than people in most of the continents/countries, but to a lesser extent, and India (87%) and Africa (82%) are the only exceptions. The chart above allows us to look at both the current trends and the future. We can …

postmarketOS is a Linux operating system that was first unveiled in 2017, with the developers aiming to provide long term support in order to extend the life of existing phones. The operating system is based on Alpine Linux with touch-screen optimization, and the goal is to provide updates, including security updates, for at least 10 years just like you would get on a computer. The project was really getting started at the time, but now the community has provided an update for the first 600 days of development, and over 100 devices are now supported, mostly smartphones such as Google Pixel 3 XL or Motorola Droid 4, but also some SBCs, for instance, Pine A64-LTS and various Raspberry Pi boards. “Supported” means the 112 devices listed can boot postmarketOS, but the operating system is still considered to be alpha software, and for example, if you look at the features matrix in the list of the device, you’ll find only LG …

Most smartphones are charged over a USB port, and many single board computers are powered by a micro USB or USB type-C port, and USB power meters such as USB Charger Doctor can be useful to evaluate phone chargers, as well as measure power consumption of SBCs. With the launch of the USB type-C connector and features such as USB PD (Power Delivery), old USB power meters are not adapted to the new standard since the connector and most importantly voltages are different, so we need USB PD compatible meters like Satechi USB Type-C power meter. Today, I decided to look for more options on Aliexpress, and you’ll find many USB-C power meters with the cheapest models going for under $5 shipped. However, ATORCH J7-c model caught my attention since it supports both USB type-C, micro USB type-B, and USB type-A power sources, so you can keep using the same meter for all your USB testing needs. ATORCH J7-c USB-PD …

Digi XBee is an ecosystem of standardized wireless module found in various development boards, and Espressif Systems ESP32 is by far the most popular WiFi and Bluetooth solution in the maker market. Somebody designed ESP32Bee combining ESP32 with XBee form factor a couple of years ago, but it was never commercialized, and I’m not aware of alternatives, except for SuperB module based on ESP32-WROOM-32 module that has just launched on Crowd Supply. SuperB modules specifications: Wireless Module – ESP32-WROOM-32 with ESP32 dual core WiSoC clocked at up to 240 MHz 4MB flash (potentially upgraded to 16MB) Connectivity – 802.11 b/g/n WiFi, and Bluetooth Classic + LE Expansion – 3.3 V levels, UART, SPI and GPIOs broken out to headers Misc – 1x user LED Power Consumption – Sleep current is less than 5 μA Dimensions – XBee form-factor compatible Certifications – Fully certified with integrated antenna and software stacks The module will be open source hardware, programmable with various tools, …
